ABSTRACT
Noroviruses are a leading cause of acute gastroenteritis (AGE) among adults and children worldwide. NoroSurv is a global network for norovirus strain surveillance among children <5 years of age with AGE. Participants in 16 countries across 6 continents used standardized protocols for dual typing (genotype and polymerase type) and uploaded 1,325 dual-typed sequences to the NoroSurv web portal during 2016-2020. More than 50% of submitted sequences were GII.4 Sydney[P16] or GII.4 Sydney[P31] strains. Other common strains included GII.2[P16], GII.3[P12], GII.6[P7], and GI.3[P3] viruses. In total, 22 genotypes and 36 dual types, including GII.3 and GII.20 viruses with rarely reported polymerase types, were detected, reflecting high strain diversity. Surveillance data captured in NoroSurv enables the monitoring of trends in norovirus strains associated childhood AGE throughout the world on a near real-time basis.

A 30-year-old man sustained bilateral simultaneous displaced subcapital fractures of neck of femur during an epileptic tonic-clonic seizure. After admission to the hospital approximately 18 hours later, internal fixation of the fractures with dynamic hip screw was undertaken. Post operatively, he was managed by early motion and weight bearing on the second day. Despite the severity of the fractures and delayed surgery, satisfactory union of the fractures was noted at 6 months when bone densitometry was normal. At 3 years follow up, there was no sign of avascular necrosis of the femoral heads.
